That's one problem I'm trying to solve now: I have a list of
checkboxes, using ids pulled from a table, and I need to figure out the
best way to encode these. My first attempt was to give each checkbox
the same name (audience, in this case) and make value=id. This works if
I don't have a validator, because the problem is, if multiple
checkboxes are selected, I get a list, but if only one is selected, I
get a single item (string).
So I did some digging and found the variabledecode stuff, and changed
my template so the checkboxes were named audience-${id}. However, it's
not obvious how to invoke variabledecode so that my method gets a
parameter called audience that is a list. Right now, it sees
audience-1, audience-2, etc. as keywords parameters (theses are being
caught as **kwargs).
What's the best/right way to solve this? It there some decorator
function to put ahead of @expose that will pre-filter arguments with
variabledecode?
